The MicroView is the first chip-sized Arduino compatible module that lets you see what your Arduino is thinking using a built-in OLED display. With the on-board 64x48 pixel OLED, you can use the MicroView to display sensor data, emails, pin status, and more. It also fits nicely into a breadboard to make prototyping easy. The MicroView also has a full-featured Arduino library to make programming the module easy.

In the heart of MicroView there is ATMEL’s ATmega328P, 5V & 3.3V LDO and a 64x48 pixel OLED display, together with other passive components that allow the MicroView to operate without any external components other than a power supply. Additionally, the MicroView is 100% code compatible with Arduino Uno (ATmega328P version), meaning the code that runs on an Arduino Uno will also be able to run on the MicroView if the IO pins used in the code are externally exposed on the MicroView.

Note: The MicroView programmer is sold separately. Check the recommended products below. Also, unlike the Kickstarter campaign, this does not come with the breadboard and USB cable. You only get the bare module.

EVB NuEdu UNO is compatible with the Arduino IDE and add-on shield NuMicro MCU uses 32-bit ARM Cortex M0 as the microcontroller core. Users can use the Arduino IDE to develop applications and utilizing open source code samples from Arduino.

NuEdu-UNO-EVB NUC131 is specific to NuMicro Series NUC131 where users can develop and verify the application program with ease. NuEdu-UNO-NUC131 includes two parts, namely NuEdu-UNO NUC131 (evaluation board) and Nu-Link-Me (Debug Adapter). By using NuEdu-UNO-NUC131, users do not need additional ICE or debug tool.

The only difference is the mini HDMI port connector from ROBOTIS OP2. Also, the location of the ports differ from ROBOTIS OP2 with respect to ROBOTIS OP. The Mode, Start, and Reset buttons remain unchanged. ROBOTIS OP2 lacks the 3.5cm microphone and audio jacks. In practice these were not implemented with ROBOTIS OP so the loss of these ports from ROBOTIS OP2 will not affect robot operations.

Advantages of ROBOTIS OP2 compared to ROBOTIS OP

As stated above the changes come in the form of an updated PC. The advantages of the new PC are listed as follows:

The Arduino Gemma is a microcontroller board made by Adafruit based on the ATtiny85 (datasheet). It has 3 digital input/output pins (of which 2 can be used as PWM outputs and 1 as analog input), an 8 MHz resonator, a micro USB connection, a JST connector for a 3.7V Li-Ion battery, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a battery to get started.

The Arduino Zero is a simple and powerful 32-bit extension of the platform established by Arduino UNO. The Arduino Zero enables creative individuals to realize truly innovative ideas for smart IoT devices, wearable technology, high-tech automation, crazy robotics, and projects not yet imagined. The board is powered by Atmel’s SAMD21 MCU, which features a 32-bit ARM Cortex® M0+ core.

Warning: Unlike most Arduino boards, the Arduino Zero board runs at 3.3V. The maximum voltage that the I/O pins can tolerate is 3.3V. Applying voltages higher than 3.3V to any I/O pin could damage the board.

The Zero board expands the Arduino family by providing increased performance to fuel the creativity of the maker community. The flexible feature set enables endless project opportunities for devices and acts as a great educational tool for learning about 32-bit application development. One of its most important feature is Atmel’s Embedded Debugger (EDBG), which provides a full debug interface without the need for additional hardware, significantly increasing the ease-of-use for software debugging. EDBG also supports a virtual COM port that can be used for device programming and traditional Arduino boot loader functionality.

The board contains everything needed to support the microcontroller; simply connect it to a computer with a micro-USB cable or power it with a AC-to-DC adapter or battery to get started. The Zero is compatible with all Arduino shields that work at 3.3V and are compliant with the 1.0 Arduino pinout.

Atmel Embedded Debugger

The Atmel Embedded Debugger (EDBG) implements a JTAG interface in order to program the on-board SAMD21 and is also connected to hardware serial of the microcontroller. This means that the 'Serial' class responds to the programming port of the board. The Arduino Zero has been designed in collaboration with ATMEL, and the on-board EDBG can be used through ATMEL Studio to get full access to the microcontroller memories to help debug your code.

Note: in contrast to some Arduino boards (e.g. Uno), when you open the serial monitor and the board is connected through the Programming Port the board does not automatically reset. You can reset the board manually if you wish to restart your sketch, for example in order to see something that is printed in the setup() function.

ARM Core benefits

The Zero has a 32-bit ARM core that can outperform typical 8-bit microcontroller boards. The most significant differences are:

32-bit core that allows operations on 4 byte wide data within a single CPU clock. (For more information see the int type page).

WIZ550S2E is the serial to Ethernet module using W5500 & Cortex-M0 MCU. WIZ550SE is the protocol converter that transmits the data sent by serial equipment as TCP/IP data type, and converts back the TCP/IP data received through the network into serial data to transmit back to the equipment.

If you use the interface board for RS232 and RS422-485, you can easily connect the module to any serial device.
